PLATFORM COVER TURNING MACHINE Filed June 25, 1962 '7 Sheets-Sheet 7United States Patent This invention relates to machines for use in themanufacture of shoes, and is herein illustrated as embodied in a machinefor turning a platform cover over a platform or midsole of a platformshoe of the type variously referred to as California, slip-lasted orforce-lasted.

In the manufacture of shoes of this type an upper, an insole or socklining, and av strip of flexible material known as a platform cover orwrapper, are assembled together oif the last, usually by stitching. Aprecemented midsole or platform is thereafter attached to the socklining, a last inserted into the shoe to shape the shoe, and the coveror wrapper is laid over and secured to the marginal portion of theplatform to cover its edge. An outsole is subsequently cement attachedto the platform, which sometimes has an integral wedge heel, to completethe shoe.

The cover or wrapper usually hugs the upper rather intimately and,before it can be laid over the platform by the lasting instrumentalitiesof the lasting machine, -must first be turned away from the upper. Theoperation of turning the cover is often performed after a last has beenforced into the shoe. In prior cover turning machines the turning isefected by grippers which engage the margin of the cover at severalpoints and pull it to turn it away from the upper either by movement ofthe grippers wmle the shoe is held stationary, or by movement of theshoe relative to the stationary grippers. In either case, such pullingaction, unless carefully controlled,v

subjects the cover strip to stresses which may damage it or even rip itaway from the upper and sock lining.

It is an object of the invention to provide a machine for turning theplatform cover at the forepart of a shoe after a platform sole has beenattached to its sock lining but before insertion of a last, wherein therisks pointed out above are eliminated.

To this end, the machine disclosed herein comprises a form engageable inthe interior of the forepart of a shoe to support the shoe while aplatform sole is attached to its sock lining, a gage movable intoengagement with the toe end of the shoe to permit an operator toregister the platform sole with relation to the sock lining, grippermeans engageable with the free margin of a platform cover at the toe endof the shoe, a fixed abutment engageable with the platform sole of theshoe when the shoe is moved oil the form, wipers engageable between thecover and the upper, and means to impart to the gripper means and thewipers movement in a direction to move the shoe off the form and tocause the wipers to move relative to the shoe after engagement of theplatform sole with the ixed abutment to turn to cover away from theupper into a plane substantially normal to the plane of the platformsole.

Preferably, and as herein illustrated, the form is constructed to beexpanded laterally within the forepart of the shoe so as to maintain thesock lining taut while a platform sole is attached, and the inventionprovides means effective to cause'the form to be expanded andconcomitantly therewith to move the gripper means and the wipers intoposition to engage the platform cover and the upper, respectively, andadditional means effective to cause the form to be contracted after theattachment of the platform sole and concomitantly therewith to rendereffective the means mentioned above which lhdfi Patented Jan. A26, 1965impart to the gripper means and wipers movement in a direction iirst tomove the shoe off the form and thereafter to cause the wipers to moverelative to the shoe while the cover is held gripped by the grippermeans to effect the turning of the cover.

These and other novel features of the invention will appear more clearlyfrom the detailed description which follows and will be moreparticularly pointed out in the claims.

and

FIG. 7 to lO, inclusive, are views in left side elevation illustratingthe positions of the operating instrumentalities of the machine iatvarious stages of a cover turning operation.

The shoe S to be operated upon in the illustrated machine comprises anupper U (FIGS. 1 and 7 to l0), to the lower margin of which is attacheda sock lining I., and a platform cover strip C which, after attachmentof a midsole or platform I to the sock lining and insertion of a last,is laid over and secured to the marginal portion of the platform in acover lasting machine to cover the wall or edge face of the platformsole prior to attachment of an outsole to complete the shoe. Before itcan be thus laid and secured to the platform, the cover which as shownin FIGS. '7, 8 and 9 occupies an upstanding position parallel to and inclose proximity to the upper, must be turned substantially away from theupper to permit the lasting instrumentalities to tension and wipe itinwardly over the platform.

To effect the turning of the platform cover C in the illustnatedmachine, the operator slips an unlasted shoe over a jack or form,identified generally by the reference character 2t? (FIGS. l, 2, 3, 5, 6and 9) and comprising an arm 22 which, as viewed from the front of themachine, that is, at the right of FIG. l, extends upwardly andrearwardly from a base plate 26 and, as shown in FIGS. 3 and 5,terminates in an enlarged, flat and wedge-shaped portion 24 engaged bythe forepart of the sock lining of the shoe. The base plate 26 is boltedyto the top of a post or frame 28 fixed to a casing 3@ rising from thebase 32 of the machine. The shoe form or jack 29 also comprises a pairof blocks 34 which, as best shown in FIGS. 3 and 5, are shaped tocorrespondsubstantially to the two halves of a divided, laterallyexpansible shoe form or last and which, when expanded in a mannershortly to be described, stretch the jacked shoe so as to facilitate:the attachment of a platform sole to the sock lining. Each block 34 ispivotally secured by a pin 36 to the upper rearwardly extending arm of asubstantially U-shaped member 3S which is hingedly mounted for lateralswingingV movement relative to the arm 22 on a bolt or pin itlprojecting upwardly from the base plate 26, the opposite sides of thearm 22 being recessed, as shown at 41 in FIG. 6, to iaccommodate the twomembers 3S. As shown in FIG. 5, each block 34 is recessed o-r rabbetedat 42 to provide clearance for movement of expansion and contraction ofthe blocks relative to the tapered rear portion 24 of the snaar/ro es deach block 34 iabout its pivotal connection to the member 3S to conformto the contour of the forepart of the shoe after the blocks have reachedthe limit of lateral expansion within the shoe.

For actuating the members 38 to cause movement ot expansion of theblocks 311, the following arrangement is provided. Extending downwardlyfrom the lower, rearwardlyextend-ing arm of each member 3d is ia pin 44which is engaged by a roll 46 carried by a pin 4S mounted in the larmsof the bifurcated upper end portion of a lever Si) (FiG. 2) pivoted at52 on a bracket 54 which is fast on the post 2S. The lower, bifurcatedend of each lever 50 also carries a roll 56. The rolls 56 engage theopposite sides ofa cam block 58 mounted for heightwise sliding movementon a bar 613 fixed at its opposite ends to cross members 62, 64 betweenthe spaced uprights of the post 28. The Ablock 58 is connected by a rod66 to a treadle 63 (FG. 1) p'ivoted at 69 on the base 32 of the machine.To the rod 66 is attached one end of a spring 71B, the other end ofwhich is anchored to the casing 3, the arrangement being such that thespring maintains the treadle normally in a position intermediate of itsupper and lower limits of movement for a purpose which will be explainedbelow.

In the rest position of the machine the rolls 56 on the lower ends ofthe levers 5@ are in engagement with the opposite sides of the upper,wide portion of the cam block 58, whereby the levers are biased in adirection such that the rolls 46 on their upper ends press :against thepins 44 to maintain the members 38 close together, as shown in FIG. 3,against 4the tension of associated springs 72 whichrtend to cause themto swing away from each other. The spring 72 associated with each member3S is attached at one of its ends to a pin 73 projecting from the lower,rearwardly extending arm of the member 4and at its opposite end to a pin'74 projecting downwardly from the base plate 26.

To the treadle 68 is also connected the lower section 75 of a two-partrod 76 (FIG. l). The upper end of the rod section 75 is threaded into abifurcated block 7S, between the arms of which is mounted a pin 88 towhich is connected one end of a link 82, the other end of which ispivoted at S3 to the lower end of an larm 84 depending from Ia bracket36 fixed to the cross member 64. Also mounted on the pin Sti is `abifurcated block $8 into which is threaded the lower end of the uppersection 9% of the two-part treadle rod 76.V The upper end of the rodsection 90 is connected to a bell crank lever 92 comprising a rearwardlyextending arm 94 and a forwardly extending, longer arm 96. rl`he arm 94is pivoted on a pin 97 mounted in rearwardly extending parallel `arms 98of a carrier 1d@ having downwardly extending parallel arms 161 pivotedat their lower ends on a transverse shaft 102 supported ilihe bracket 86and upwardly extending parallel arms Between the upper ends of thespaced parallel arms 163 of the carrier 10@ there is provided a block164 (FiGS. 1, 3 and 7-10) formed with forwardly projecting lingers 106arranged to contact the outer face of the platform wrapper at oppositesides of the tip of the shoe, when the carrier is caused to swing intooperative position in a manner to be described shortly, and to cooperatewith complemental fingers 168 adapted :to engage the inner face of thecover. The fingers w8 are integral with a pair of parallel arms pivotedat their forward ends on a pin or bolt 112 extending through the block1de. The arms 11E) are connected by universal joints 114, rods 116 anduniversal joints 11S to the opposite ends of a whiiiietree 121i (FlGS. 3and 4) mounted for rocking movement about a bolt 121 extending into thearm 96 of the bell crank lever 92. To the upper surface of the arm 96 issecured by a screw 12,2 a T-shaped leaf spring member 123, the cross barof which overlies the whiiiietree 12@ and tends to maintain it incondition of equilibrium. This arrangement permits equalizing thetension exerted on the platform cover by the gripper lingers 193 at theopposite sides of the toe end of the shoe.

On each end of `the bolt 112 is mounted for rocking movement about thebolt a cam member s (FiGS. 1, 3 and 7-10) `to which is secured one endof an arm 126 consisting of a str-ip of flexible metal, such as springsteel. To the other end of each arm 12d is xed a blade or wiper 128which, when the carrier 1&5 is swung in one direction, is moved into aposition between the piatto-rm cover C and the upper U a. the side ofthe shoe S and which during the reverse swinging movement of thecarrier, is moved in a direction to turn the cover from the positionshown in FIG. 7 to that shown in FIG. l0. To a pin 13d projecting fromeach cam member 124 is attached one end of a spring 132, the other endof which is attached to the underside of the adjacent gripper arm 11d.in the rest position of the machine the springs 132 maintain the coverturning wipers 12S and the cam members 12 in the positions shown in PiG.1 in which each cam member is in engagement with a roll 134 (FIGS. l, 3,9 and 1G) mounted on the forwardly projecting portion of a bracket 136secured to each of a pair of spaced uprights 13S mounted at their lowerends on the shaft 192 and joined together at their upper ends by a crossmember 14d. The structure formed by the uprights 138 and the crossmember 14? is connected by members 142 lto the opposite sides oi abracket or frame 144 secured lto the cross member 52.

The assembly described above is under the iniiuence of a spring 146(FGS. l, 9 and 10) attached at one end to a pin 143 projecting from thecarrier 161i and at its opposite end to a pin 15G projecting from thebar dll, the said spring tending to cause the carrier 109 to swingclockwise from `the position shown in PEG. 1 to that shown in FiG. 7.T-'he assembly is held in its retracted position sho-wn in FlG. 1,against the tension of the spring 146, by engagement of a detent 152(FIG. l) fixed between the rearwardly extending arms 93 of the carrier iwith a pawl 154 fast on a rockshait 156 mounted in the uprights 138.Also fast on the shaft 156 is one end of a link 153, the other end ofwhich is pivota-lly connected to 4the lower end of a rod 166 extendingthrough a plate or bracket 162 fixed to the cross member 140. The upperend of the rod 166 is provided with a knob 164 between `which and theplate 162 is interposed a spring 1&6 surrounding the upper end portionof the rod lett.

The operation of the machine thus far escribed is as follows, Theoperator mounts the orep-art of an un- -lasted shoe S in invertedposition on the jack or form 20 (FlG. 1) comprising the arm 22 with itsflat wedge-shaped portion 24 and the blocks 38, which at this time arein the closed or contracted positions. He then presses the knob 164 and,the rod 160 being depressed, the link 158 is .caused :to swing clockwiseand the shaft 156 is rocked in the same direction, disengaging the pawl154` from the detent 152 and releasing the assembly comprising thecarrie-r 169, on which are mounted the gripper fingers 196, 1118 and thecover turn-ing wipers 12S, to the .action of the spring 146 which causesit to swing in a clockwise direction from the position shown in FIG. 1to that shown in FIG. 7. When the knob 164i is released, the rod 160 is.returned to its initial position by the spring 165 and causes the link153 to swing in counterclockwise direction to locate the pawl 15d inposition to `be engaged by the detent 152 to lock the carrier when lthetre-adle 63 is released at the end of a cover turning operation.Movement of the link 15S in that direction is limited by a stop pin 167(FlG. 1) projecting from one of the bars or uprights 133.

As the assembly' is thus unlocked, the treadle 63 which, las previouslynoted, is held by the spring 7@ in an intermediate position when theassembly is locked, is raised by the spring. As the treadle rod 66 movesupward, the

cam block 58 move upward along the slide bar dil and the oppositeinclined sides 58a of its lower portion (see FIG. 2) are engaged by therolls 5o on the lower ends of `the levers 50, which are thereby causedvto swi-ng oppositely :outward and away from the pins 44 depending fromthe lower arms of the members 33, so that these members and the blocks54 carried by them may be swung by the springs 72 in a direction toexpand laterally within the forepart of the shoe and support it iirmlywhile Ithe operatorattaches a platform to the sock lining.

When the carrier 109 swings clockwise, a toe gage lS (FIGS..1 and 7 tol0) is moved into engagement with the .toe end of the shoe, the gageprojecting somewhat above the level of the sock lining L to enable theoperator to locate a platform P on the sock lining. The toe gage 168forms one arm of an L-shaped lever 171i, the other arm 172 of whichterminates in a bifurcated block 174 which is fulcrumed on a pin 176mounted in a lug 177 projecting from the block 164 between the arms 1&3of the carrier 10G. The lever 17@ is normally held in the position shownin FIG. 1 by a tension spring 173 attached at one end to the lever arm172 and at its opposite end to lthe pin 14S which projects from thecarrier. As the carrier 1mi swings from the position shown in FlG. 1 tothat shown in FIGS. 7 and S, the undersurface of the lever `arm 172,somewhat to the left of the rounded lower edge of the block 174, isengaged by a roll 189, and the lever 17d is swung clockwise about thepin 176, against the tension of the spring 178, to loca e the gage inoperiative position. The -roll 13@ is carried by a pin 182. mounted inthe bifurcated rear end portion of'a block 184 pivoted at its forwardend on a pin 186 mounted in the upwardly extending arms of the bracket14d. The block 184 is maintained by a spring 13S, which is connected atone end to the 'block and vat its other end to the bracket 1M, againstthe upper end of adjusting orew 1% threaded through a boss 192 of thebracket 144. By adjustment of the screw 19t? the level of the rearwardend of the block 184 may be varied so as to vary the extent of clockwiseswinging movement of the lever 17? to locate the toe gage los indifferent operative positions according to differences in the sizes ofshoes mounted -on the form or jack 2%. A nut 19d locks the screw 19? inthe adjusted position.

Movement of the carrier 1Gb to the position shown in PEG. 7 moves thefixed upper gripper fingers lilo projecting from the block HB4 disposedbetween the upper ends of the rarms 1i3 of the carrier into engagementwith the outer face of the cover strip C, while the lower lingers 198formed integral with the pivoted arms 11o are moved into a positionbetween the cover and the upper. A-iso, as the carrier 1% is unlatchedand the cam members 124 which carry lthe lcover turning wipers 128 .aremoved out of engagement with the .rolls 134 (FlG. 1), the springs 1.32,which are attached to the pins 136 on the cam members, swing the cammembers in a clockwise direction to locate the wipers in thesubstantially horizontal position shown in FiG. 7.

The operating instrumentalities of the machine occupying the positionsshown on FIG. 7 and the forepart of the s'noe being stretched on theform Ztl, the operator spots and ,attaches by hand to the sock lining La precemented platform P, utilizing the gage 158 to register theplatform correctly with relation to the sock lining. He next depressesthe treadle 68. During the first portion of the downward movement of thetreadle, the treadle rod 76 swings the lever 92 about its fulcrum 97 ina clockwise direction to rock the gripper amis 110 counterclockwise,iirst to the position shown in FIG. 7, to bring the gripper ingers 108into engagement with the free margin of the cover C at the tip of theshoe, and then to the position shown in FG. 8. As the :arms 110 rock inthat direction, they impart, through the pins 130 carried by the cams124, movement in the same direction to the cams to move the wiper blades128 from their horizontal d position shown yin FIG. 7 to that shown inFIG. 8, where they engage the sides of the shoe, the spring arms 126 towhich the blades are secured yielding laterally to enable the blades toaccommodate themselves to the width of the shoe.

When the gripper ngers 108 reach the position shown in FIG. 8, with themargin of the cover C at the tip of the shoe engaged between them andthe fixed upper gripper fingers 166, the gripper arms 110 and theiringers 1118 become rigid with the carrier 100. Thereafter, as thetreadle is depressed further, the assembly comprising the carrier 16@and the gripper members is rocked as a unit,

coun'terclockwise about the shaft 102, from the position shown in FIG. 8to that shown in FIG. 9, overcoming the force of the spring 146 whichtends to urge the carrierV to swing clockwise.

As the treadle is depressed, the treadle rod 66 (FIG. 1) moves the block5S downward to the position shown in FIG. 2, where the sides of itsupper, wider portion are engaged by the rolls Se on the'lower ends ofthe levers Si), causing the levers to swing oppositely inward to bringthe rolls 48 at their upper ends into engagement with the pins 44carried by the members 3S, whereby these members are caused to turnabout their pivots d@ (FIG. 1) toward each other to move the blocks 34from their expanded position shown in FlG. 5 to theirorginal contractedposition, so as to release the shoe. s

When the carrier litt) is swung away from the position shown in FIG. 8toward that shown in FIG. 9, the arm 172 of the lever 17o moves oif theroll 186 carried by the block 1&4, and the lever is returned by itsspring 178 to its initial position, moving the toe gage 16S away fromthe shoe.

As the grippers 1tl8, in engagement with the inner face of the cover,are moved with the carrier 100, they pull the shoe ott the form 20 in arearward direction until the wiper cams 124 again engage the rolls 134and are rocked counterclockwise, as seen in FG. 9, causing the wipers123 to turn the shoe in a counterclockwise direction into thesubstantially vertical position shown in FlG. 1t), where the platform Pon the shoe engages a fixed abutment 198 secured to a bracket 200 whichextends upwardly from a plate 202 fixed to the cross member 14d. As theshoe is turned by the wipers while the cover is held clamped between theupper and lower grippers, the margin of the cover at the tip of the shoeis turned outward about The shoe now being held by the abutment 19Sagainst further movement, and as the operator continues to depress thetreadle, the Wipers 12S are moved relative to the shoe to complete theturning of the cover C away from the upper U until it occupies la planesubstantially at right angles to the plane of the shoe bottom.

At this point the operator releases the treadle and the carrier lll,which had been moved to a position somewhatrfurther to the left of thatshown in FG. 1, is swung clockwise by its spring 146 until the detent152 engages the pawl 154 to lock the carrier in its original startingposition. During such clockwise movement of the oarrier, the arms arecaused to swing clockwise to move the grippers 1% to their open positionso as to permit the operator to remove the shoe. The clockwise swingingmovement of each arm 110 is yieldingly limited by engagement with theunderside of the cross member 141i of a leaf spring 29d secured to eacharm.
